Description
This security bulletin contains information about 12 vulnerabilities.
1) Input validation error (CVE-ID: CVE-2007-6716)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation within the direct_io_worker() and __blockdev_direct_IO() functions in fs/direct-io.c. A local user can perform a denial of service (DoS) attack.
2) Improper input validation (CVE-ID: CVE-2008-2372)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The Linux kernel 2.6.24 and 2.6.25 before 2.6.25.9 allows local users to cause a denial of service (memory consumption) via a large number of calls to the get_user_pages function, which lacks a ZERO_PAGE optimization and results in allocation of 'useless newly zeroed pages.'
3) Integer overflow (CVE-ID: CVE-2008-3276)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow error. A remote non-authenticated attacker can perform a denial of service (DoS) attack.
4) Permissions, privileges, and access controls (CVE-ID: CVE-2008-3525)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to execute arbitrary code.
The vulnerability exists due to security restrictions bypass error. A local user can execute arbitrary code.
5) Integer overflow (CVE-ID: CVE-2008-3526)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow error. A remote non-authenticated attacker can perform a denial of service (DoS) attack.
6) Resource exhaustion (CVE-ID: CVE-2008-3534)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to resource exhaustion error. A local user can perform a denial of service (DoS) attack.
7) Off-by-one error (CVE-ID: CVE-2008-3535)
CWE-ID: CWE-193 - Off-by-one Error
CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to perform a denial of service (DoS) attack.
Off-by-one error in the iov_iter_advance function in mm/filemap.c in the Linux kernel before 2.6.27-rc2 allows local users to cause a denial of service (system crash) via a certain sequence of file I/O operations with readv and writev, as demonstrated by testcases/kernel/fs/ftest/ftest03 from the Linux Test Project.
8) NULL pointer dereference (CVE-ID: CVE-2008-3792)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to NULL pointer dereference within the sctp_setsockopt_auth_chunk(), sctp_setsockopt_hmac_ident(), sctp_setsockopt_auth_key(), sctp_setsockopt_active_key(), sctp_setsockopt_del_key(), sctp_getsockopt_maxburst(), sctp_getsockopt_active_key(), sctp_getsockopt_peer_auth_chunks() and sctp_getsockopt_local_auth_chunks() functions in net/sctp/socket.c, within the sctp_endpoint_init() function in net/sctp/endpointola.c. A remote non-authenticated attacker can perform a denial of service (DoS) attack.
9) Resource management errors (CVE-ID: CVE-2008-3831)
CWE-ID: CWE-399 - Resource Management Errors
CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The i915 driver in (1) drivers/char/drm/i915_dma.c in the Linux kernel 2.6.24 on Debian GNU/Linux and (2) sys/dev/pci/drm/i915_drv.c in OpenBSD does not restrict the DRM_I915_HWS_ADDR ioctl to the Direct Rendering Manager (DRM) master, which allows local users to cause a denial of service (memory corruption) via a crafted ioctl call, related to absence of the DRM_MASTER and DRM_ROOT_ONLY flags in the ioctl's configuration.
10) Buffer overflow (CVE-ID: CVE-2008-3915)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The vulnerability exists due to memory corruption within the init_state() function in fs/nfsd/nfs4acl.c. A remote non-authenticated attacker can execute arbitrary code.
11) Information exposure (CVE-ID: CVE-2008-4113)
